Ad-hoc is only specified to 11Mbit/sec connection speed. Some
wireless devices will go faster in ad-hoc mode, but it's NOT
officially supported.

Maximum thruput is roughly half the connection speed. See table at:
<http://wireless.wikia.com/wiki/Wi-Fi#Performance_and_Speed>

The Intel 2200BG will only do 54Mbits/sec, which will give you a
maximum throughput of about 25Mbits/sec.

100baseT-FDX over CAT5 will do about 80-90MBits/sec. Gigabit ethernet
will go even faster. Making disk images requires that the transfer
NOT be interrupted, which unfortunately is a common wireless problem
when interference stops the transfer. If you want speed and
reliability, I suggest you consider a wired solution, instead of
wireless.
